    NT555R Performance. The Nitto Extreme Performance NT555R is a D.O.T.-compliant competition drag radial designed with maximum flexibility for the weekend drag racer. The NT555R combines a high grip compound and semi-racing construction to provide maximum traction at the starting line. The tire comes molded at 6/32 of an inch and features a unique reinforced belt package to provide improved traction and high-speed stability. The NT555R is the perfect performance radial for the street or strip.

    Maximum-Traction Racing Tread. NT555R's are manufactured with the original tread depth of 6/32nds" and are constructed with a specially formulated soft racing tread compound to provide maximum traction. High block rigidity, soft compounding and large contact patch provide extreme dry traction in race conditions. Low void ratio and large tread blocks optimize dry traction.

    Summer Track Compound. The NT555R's compound is specifically designed to provide maximum sticky grip in the warm months on the street and the track. A reinforced belt package further improves handling and helps to prevent against punctures for road use.

    Application. The Nitto Extreme Performance NT555R Drag Radial is a unique ultra-high performance tire that's also D.O.T.-approved, making it perfect for any street/strip Mustang owner.

    NOTE: This is a high-performance tire intended for use during summer months or warm temperatures only. Use during cold weather will greatly reduce performance, traction and handling, and greatly increase stopping distance. If using this tire in a drag or track environment during cold weather, we strongly recommend performing a pre-run burnout to nominalize the tread compound's temperature.

    Would these fit on my '03 Cobra if it is lowered 1.4 inches in the rear? I have a set of 18x10 Saleens in the rear and was wondering if the radial would fit my car seeings how it is lowered. Thanks!


    • Yes sir no problem

    will this tire fit on my 20x10 bullits? fit under my 07 GT? If not what is the largest i can go? The package came with 285s on the rear.


    • The NITTO Extreme Performance NT555R Drag Radial in a 305/35-20 will certainly fit on the 20x10 wheel. Depending on the amount which your vehicle is lowered and if any spacer is on the hub, it could cause some rubbing on the fender. If you could contact us at your earliest convenience, we would be more than happy to confirm the fitment on you specific set-up :)

    My car is currently on 245/45zr17 would the 315/35/17 fit


    Currently my car has these tires in 305/35r18, i am a little hesitant to spend the additional money for the 35 aspect ratio. My car only makes low 300's rwhp. The car grabbed well and handled amazing with the 35, do you think there will be a big difference if i cheap out a little and go with the 305/45r18 instead?


    Will a335 30 18 fit on a2007 gt


    • A 335/30R18 NITTO Extreme Performance NT555R Drag Radial can be installed on a 2007 GT however a wheel with a width between 11.5" and 12.5" would be required, and you may experience slight rubbing. We do not recommend this size for street cars, or cars that are lowered.

      Review from NITTO Extreme Performance NT555R Drag Radial - 305/40R18 (79-18 All)

      No more spinning!

      I had some not so good yumitomos on the stang and with these nittos I actually grip from a dig. No more wheel spin whatsoever. Makes the car look awesome too! Amazing what just new tires can for both performance and looks.

      Really good traction, but 1000 miles in, tread is going down like crazy. BUT, I know what i paid for, and that is the performance, and I got that out of this tire.

      Works as advertised

      Great drag radial, could be used as a street tire, but wont do well in the rain, and due to its soft compound, it wears pretty quickly.

      Lasted about 5k miles before bald. Not for the hot sun in AZ. Soft tire with great grip tho. They do run narrow. In the heat its just not the right tire..600 in tires should last a little longer..Was expecting 15k miles. Spirited driving no burnouts
